Wireless access point daemon, patched with ubus support

When wpa_supplicant receives a request to start a P2P group owner on a fixed frequency with bandwidth wider than 20 MHz, wpa_supplicant scans for neighboring BSSs prior to starting the GO. This is done to switch the primary/secondary channels if there are any other networks which are operating on the same secondary channel. Though this logic is defined for 20/40 MHz coexistence and might improve throughput, there are P2P use cases where this logic causes problem: 1. The file transfer use case takes time to start the file transfer or even fails when the 20/40 coex scan repeatedly fails due to an ongoing externally triggered scan happening in the system. 2. wpa_supplicant overrides the channel which is selected by the application based on the best channel it derived by looking into the channel conditions. This degrades the expected throughput. 3. Latency sensitive applications experience long time to start the group owner which gives a bad user experience. So do not allow 40 MHz co-ex PRI/SEC switch to force a change to Autonomous GO PRI channel when the P2P group add is called with a forced frequency. Test: Tested autonomous GO and confirmed from the logs that P2P GO is not triggering 20/40 coex scan. Signed-off-by: Sunil Ravi <sunilravi@google.com> |

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2022, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These programs are licensed under the BSD license (the one with advertisement clause removed). If you are submitting changes to the project, please see CONTRIBUTIONS file for more instructions. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
